TOP PLATE FOR REGISTERS.

SPECIFICATION forming part of Letters Patent No. 749,116, dated January5, 1904.

Driginal application filed May 20, 1902, Serial No. 108,148. Divided andthis application filed July 12, 1902. Serial No. 115,371. (No model.)

To all whom it may concern:

Be it known that I, HARRY J. VALENTINE, a citizen of the United Statesof America, and a resident of Hempstead, Nassau county,New York, haveinvented certain new and useful Improvements in Top Plates forRegisters, of which the following is a specification.

This invention relates to top plates for registers for hot-air furnacesor for those used for ventilating purposes; and the object of the sameis to provide a top plate or cover for the purpose stated which will bestrong and substantial, which may be composed of sheet metal, and bywhich it is possible to impart a certain degree of ornamentation andlightness.

To these ends myinvention consists of certain features of constructionto be hereinafter described and then particularly claimed.

In the accompanying drawings, Figure 1 is a perspective View of aregister viewed from a point to show the top plate to advantage. Fig. 2is atransverse section of the top plate on line 2 2, Fig. 1. Fig. 3 is alongitudinal section thereof. Fig. 4 is a transverse section on line 4.4:, Fig. 1. Fig. 5'is an under side view of a portion of one end only ofthe top plate, the other end being constructed the same. Figs. 6 and 7are detail views showing how the bars of the grillework are secured inposition. Fig. 8 is a detail side elevation of one of the bars of thegrillework, showing how the same is twisted to produce a flush uppersurface throughout.

According to the present invention the topplate is preferably made ofsheet metal bent into suitable shape and composed of four side pieces KK K K, Figs. l to 8. Each of the side pieces is composed of a strip ofsheet metal folded longitudinally along the median line, there being acertain fullness between the ends of the samethat is to say, theparallel sides are not mashed down close together, but are spaced asuitable distance apart to provide thickness and strength. The ends ofthe side pieces K K are pressed together and inserted between the openends of the side pieces K K. At the joints so formed the parts areconnected by means of suitable rivets Z. This part of the structure isclearly shown in Fig. 2. Shoulders 1'1 are formed transversely of theside pieces K K, respectively, so as to abut against the adjacent edgesof the same and to thereby impart additional strength and firmness tothe rectangularfrarne of the top plate. Between the side pieces K K arelocated and secured bars M, which form the grillework or ornamental workof the register. Details of these bars and the means for connecting themwith the top plate are shown in Figs. 6, 7, and 8. The bars are eachcomposed of a body wt, and the ends m thereof are disposed at rightangles to the plane of each bar, the upper or outer surfaces of ends mbeing flush or substantially flush with the outer or upper edge of thebody of the bar, this being preferably effectuated by twisting the barat both ends at m so that the ends 'm are located to one side of andparallel with the longitudinal axis of the body m. In this way thegrille or ornamental work, which is composed of these bars, has anornamental effect imparted thereto by the twist formed in the bars, andat the same time the bars are strengthened against flexure in anydirection. The bars are of greater length than the distance between theinner edges of the side pieces K K, and the ends m of the bars areinserted in the longitudinal recesses formed by doubling the end pieces.The bars are firmly retained therein and spaced at suitable intervalsapart by crimping or stamping the inner sides of the side pieces betweenthe ends of thebars to form depressions on the outside of the inner sideportions of the side pieces which at the inner side form shoulders mthat stay the bars against lateral motion.

,As a further security against shifting of the bars the inner portionsof the side pieces K K are formed with stamped teats n, which entersmall depressions 'n in the ends of the bars.

What I claim as new, and desire to secure by Letters Patent, is-

l. The herein-described top plate for registers, the same comprising aframe composed of suitably-joined pieces of doubled sheet metal, the endof one piece at each joint being left open to receive the end of theother piece, the sides of which are pressed together, and bars extendingacross the frame, and the ends of which are retained in the same,substantially as described.

2. The herein-described top plate for registers, the same comprislng arectangular frame composed of sheet-metal strips doubled lengthwise onthemselves and formed with overlapping riveted joints at the corners,the end of one piece at each joint being left open to receive the end ofthe other piece, the sides of which are pressed together, and grille orornamental work secured within the said frame between opposite sides ofthe
